The o ject ,of my invent-ion is to so construct an 'apparatus of Athe inclined lane t i ering'ii'n wei'g itijl'nd hulk rn'f'ny bejlowered .at or about thelsanle frate of'speed.

the device illustrated-in' Fi `1; Figs. 4, 5, 6, 7` andS, 'are views of motltications ofthe invention.

In this instance A is a buildinlgiandia Vthe different oors of the'building.. )Extending throu h the building' is 4 a' well IA in which is t le'inclined plane B in the form of aspiral. -The floor b of the inclined plane is'secured in any suitable manner to the central standard B'.

cushion' c supported on the foundation of the structure; this elastic cushion maybe either made of rubber-or in the form of a metallic spring. The inclination 'of the floor b of the spiral inclined plane is at au angle less than the an le of slide of the material to be transferre from the^upperlioors` to the lower floor, so-that when the in* clined )lane B is at. rest the material will no tslit e, and in order to makel the 'material slide I provide means for hn arting a. tremor to the inclined plane-and t is tremor will give suliicient lnotion to the material As illustrated in Fig. 3,- the base of this standard rests in un elastic mounted on' the' inelinedf plan elitist? il?` to more and, conseqx'ientfly,-'the ioveinont will he downward' owing td'tl\e-in'"e'li'i1tioii "l1 'of the AFloor of the plane.'l .5.12 l' ,7: .i'i. of. 60 -fln sundryv ex erimets Ifhave foiindlfthti materials of di4 erent- 'weightwillltiaifelfftiril this ilnproved apparatusvut aboutthes'iihie speed, It will be uuderstoodtthrtilfferf=th1 "il package is placed' on'- theQinclin'edbpla ol- )e delivered atthe lower end'fitisnot neces? sary that it should travel (lewinwal-"dfia'tlyi'2 great speed g. lnl fact consulentileitnp'e can" elapse".between the delivery "guidiffdiscliarlje' "i5 without interfering with 'lthe' 'rontiiebuHil- 70 tion thcspeed of travel is suclrlthat ltlie'heavyt 80 packagegcailnotf ma intain.=:su'el,r: :'x; spec-dn tha't .th contents-would bef lia-ble to hreilkfsllonldf -the `package come-'to arjsudden"" optlnoil wouldit. crush into. a. smaller pafckngefandr'Ell 4.injure the contents, l.iut tlicftwazpzu-.kiges 85 'would travel slowlyidou'nto-fthe oiiitmfn idlSCllll'gC. 1." -There .are several means'forE iinpaitin'gv'zh- "tremor to'vthe iiic lined 'pla'ne vandfa'n'y fsuit" able vibrator` may be used fortthisapnrpo such a device is shown, forf-instancel-inlfig 1 and 2, and may he mounted on\ tliehupperi end of the standard' ofthe inclinedplanc'; B. Theldevice consists of a solenoid I) carrying a yoke e mounted on the 'end of the 'standard B', and on the yoke is a pin c mounted in a bracket E; the pin may be cushioned in a bracket in any suitable man ner. An armature l is mounted -in the solenoid and has .a disk Il', and there are springs J2, d, one on each side of the disk, and one spring is heavier than the other, as lshown in Fig. 8. The cushions at the upper and loweiends of the inclined plane are for the purpose of'prcventng the tremor action being imparted to' the building. iVil-es lead to the source of u low'frcquency alternating current so that, when the current is switched Ainto the solenoid the action of the solenoid will cause the entire s iiral strueture'to trein'- ble, so that any artic e plaeed'on the strucpiane-to the point of discharge. A'Suitable` openings a.may be rovided at each. floor i for the placin of art les o f merchandise on the inclined p ane, and there is an' opening at the base for .the free discharge of the rrerchandise..

In Fig. 4, I haveshown a sprin`g`cushiqn l c" in place of the .rubber block illustrated i'n llo Fig 3, and in this view I have shown side springs c for taking up the shock.

In Fig. 5, `I have illustrated a series of vibrators vD placed at'intervals under the floor of the spiral inclined dplane, and these vibrators can be constructe in any suitable manner and connected to any means for imparting a slight tremor to' the structure.

These vibrators may be in the form of a solenoid -as in Fig. 8, or may be in the form of a motor having an arm on the armature out of balance so as to give a trembling a'ction to the inclined plane.

In Fi 6, I have shown a modification in which ere are straight inclined'pla-nes b2 connected to curved planes-b'. In this instance the trembling motion is only im art-- ed to the curved planes and the ang e of' these planes '1s ls than the sliding angle for the material, while the straight planes b' are at the angle of slide 'of the material so that'w'hile the material is free to slide'on the straight planes it will be retardedon the curved planes and this retarding action will prevent the too rapid descent o f the material from a high elevation to the point of discharge.

Other means for imparting. this tremor may beresorted to without. departing from the essential features of .my invention, and

the inclined planemay bemade in other formsthan that of a spiral. In factin some instances it may be in a straight line as in Fig. 7, placed at such an angle that`the I naterial will not move unless a tremor is imparted to the plane. Y In this' figure the' solenoid D is attached to the underside' of the plane b' which isinounted on cushions c -c at each end.

I claim v inclined plane forim arting a slight tremor 1. The combination'of an inclined lane tothe said inclined p ane so-as tocause fnaterial to move slowly in the direction of the least resistance.

2. flhe combination of an inclined plane, a casing in which the inclined plane is situated, means carr1ed`by the inclined plane for. imparting a tremor thereto and an elastic support between the inclined plane and the' casing.

3. The combination of a building a spirally; arranged inclined plane, the oor of the' incline plane being at an angle-less than the angle of slide o the material to be transported, with :1 -vibrator mounted on the underside of the inclined plane for imparting a tremor thereto.

4. The combination of an inclined plane for "transporting materials, arranged in' a s iral, the carrying surface of the inclined p ane b'ein arranged at anan le less than the angle o slide of the materia to be transported, and a series of electrical de viceslocated on the -underside of the inclined plane for imparting a tremor thereto.

In testimony whereof, I have signed my two subscribing witnesses.
